Teaching Materials

Short Bio

I am an assistant professor at Université Paris-Sud. I am teaching at Polytech Paris-Sud and I am a researcher in the ExSitu team which is a join research group between LRI and Inria Saclay. My research interests include computer human interaction, remote collaboration in interactive systems, telepresence, virtual environment, 3D interaction and 3D reconstruction.

After achieving a Bachelor of Science degree in mathematics at the Université de Bretagne Sud (UBS Lorient, France) in 2004, I obtained both a Master of Science degree in computer science and a Master of Research degree in image processing and artificial intelligence from the Institut National des Sciences Appliquées (INSA de Rennes, France) in 2008. During these years, I juggled my studies with sailing at an international level in the 49er Olympic class.

Postdoctoral work

Description: The purpose of this postdoctoral fellowship is to work on acquisition and reconstruction of 3D real scenes for telepresence system. Particularly, it aims to improve the 3D reconstruction of users' faces captured by a low quality range sensor (as a Microsoft Kinect for example). This kind of range sensor has the advantage to be cheap and accessible to everyone. The main idea is to use some high quality models of the users' heads to improve the low resolution input of the range sensor. Moreover, this work could also be used in order to transfer only a small among of data for the depth on the network during a 3D telepresence session. This postdoctoral work is done in the context of the BeingThere Centre.

PhD work

Description: Virtual reality enables several remote users to meet themselves in a shared virtual environment to perform collaborative work such as a simple observation or a co-manipulation of virtual objects. The technical constraints, the different material devices used by each user and the fact of being in a virtual world increase the complexity and consequently the misunderstanding between users. My PhD work aimed to improve this collaboration between remote users by proposing new models for designing a collaborative virtual environment. These models deal with the network distribution, the software architecture, but also the integration of new metaphors for collaboration. This PhD was supported by the French National Research Agency (ANR) in the context of the Collaviz project.

Collaborative experiment between Rennes and London: all the models proposed during my PhD have implemented in a new framework for collaborative virtual environment and this framework has been used to set up a collaborative experiment between Rennes and London. The goal of this experiment was to compare a single user manipulation and a remote collaborative manipulation for examining some scientific data. The users have to manipulate a clipping-plane to make a cross section of the data. In the following video, you can see the collaborative manipulation: one participant in Rennes (France) and one participant in London (United Kingdom) manipulate together a clipping-plane using a three-point manipulation technique. This experiment has be done in the context of the Visionair project funded by the European Commission.
